I think you meant insufficient storage on iCloud. In that case, you can either upgrade your iCloud storage to higher capacities through subscription, or backup your iPhone, iPad or iPod Touch to your PC or Mac using iTunes. For the Time Capsule, it can only be used for Mac backups, not iOS Devices.

I am thinking of upgrading to a Time Capsule as my primary router and WiFi connection at home. If I needed more wired connections (say 3-5 more) can I simply add a wired network switch to one of the connections on the back of the TC?

I was looking at exactly the same situation, so here's what I've learned, hope it is useful.

The Mac OS X system requirements for setting the AirPort time capsule require Lion 10.7.5 for setup and administration — however if you have an iPhone/iPad device running running iOS 5 and also have AirPort Utility 1.3 (free from the App Store) it is possible to set up and administrate the unit wholely from your iOS device.

All other features should work fine, as:

- Time Machine backups are supported from 10.5.7+
- Shared printing is supported from 10.2.7+
- Sharing a connected USB hard drive is supported as of 10.4.8

Technically, any wi-fi enabled device should be able to connect to the module once set up. — The one handicap you will face is the need to set your device up from an iPhone/iPad.

Note: I hear the user interface on the iPad app is the best, as it provides the best information about your devices.

Yes, no problem. The Time Capsule will create a separate folder for each device. Just bear in mind that later down the road, those devices will likely be fighting for space as the Time Capsule fills up!

Apple doesn't recommend specific ADSL modems for use with the base station. Any standard ADSL modem with an Ethernet port should be compatible (you cannot connect the modem to the base station via USB). If you're not able to use the AirPort with a particular ADSL modem/configuration, it is unlikely that you would be able to use any other wireless base station with that modem and configuration.

Yes, I will even say better. The actual hardware its self is the same thing your normal external seagate or western digital would have without the wifi of course. Hard drives companies like Seagate and WD make their versions of Network Attached Storage (NAS) but aren't as user friendly as most would like. I have owned a Apple 2TB Time Capsule for quiet some time and wouldn't ever go back to anything else. I still use regular external hard drives for odd and end things but mainly use my Time Capsule. Being able to wireless transfer data and storage option for multiple devices is the amazing thing about it.

No. Just one of the many things some of us wish were configurable on Airports. The hardware is nice, works well, and is pretty easy to configure and maintain. But in some ways it is really lame. This is one of those ways.

Time Machine is a software program you can use to backup your mac to an external hard drive.

Airport Time Capsule is a physical device that you plug in at your home/office & it offers fully automated backup for computers on your Wi-FI network. The Time Capsule is also a fully featured Airport Extreme base Station that provides simultaneous dual-band wireless networking using the 802.11ac specification.

If you have a Mac computer set up to serve to back up your iPhone and iPad then you can use the Time Capsule to back up your Mac computer (with the iPhone and iPad files on it) so that will keep track of your data on your devices. It can be set to either save your iPad, iPhone data wirelessly whenever they are plugged in to charge or to save when they are attached to your Mac computer.
The Airport Time Capsule saves your Mac computer data at whatever interval you set it for so you have multiple sets of your files that you can restore back to.

I have a Canon Pixma wireless printer that can only connect to WiFi via WPS. I have a Time Capsule 2TB router. I do not see a WPS button on it. Is there a way to trigger the WPS functionality via some other means? In other words: without using a USB cable, because that is connected to my wife's desktop PC, how can I virtually press a WPS button on my Time Capsule to connect the printer to my apple network?
